OF PONTIAC, ILLINOIS MECHANICAL HOIS'I. END GATE Application filed June11,

This invention relates to certain new and useful improvements in hoistsof a type designed for raising and lowering a vehicle endgate whiledisposed in a horizontal plane.

One of the principal objects of the invention embodies an operatingmeans for the endgate to beincluded upon and, operable from the vehiclepower plant.

Another object of the invention consists in the arrangement of guidesfor the endgate to obviate undue interference to the elevating mechanismand distortion of the endgate while in use. i

More specifically stated the guides are pro vided with journals wherebythe endgate may be swung to occupy the conventional positions.

With the above and other objects in View, the invention further consistsof the followtion, to be hereinafter more fully described, illustratedin the accompanying drawings and pointed out in the appended claims.

' Inthe drawings:

Figure 1 is a rear elevation of a motor vehicle truck body showing theendgate in elevated position andjswung in avertical plane {)0 partiallyclose-the rear end of the wagon ox.. V Figure 2 is a fragmentary sideelevation of the truck body illustrating by full and dotted lines therespective positions capable of being attained by the endgate throughthe operation of the hoist. I

Figure 3 is a horizontal sectional view taken through portions of theguide and hoist mechanism respectively.

Referring to the drawings in detail where'- in like characters ofreference denote corresponding parts, thereference character 10indicates generally a motor vehicle chassis having a truck or deliverybody 11 of conventional construction.

Attaching plates 12 secured upon the outer 45 and opposite sides of thebody 11, in vertiing novel. features and details of construe-- 1930.Serial No. 460,499.

cally disposed planes and immediately adjacent the rear entrance to thebody or wagon box, are provided with outstanding ribs or fins 13. Bars14 of circular contour are carried upon the outer portions of the finsor ribs 13 spaced from the attaching plates 12.

Sleeve members 15 split, as at 16, to accommodate the fins 13 aretelescopically associated with the bars 14 in loose fitting relation,the purpose of such connection will be presently apparent in thefollowing description of the invention. Disk members or wheels 17journaled within the ends of the bars 14 in the manner shown in .Figures1 and 2 of the drawingshave the peripheries therefor extended outwardlyfor appreciable distances beyond the outer surface of the immediate barsfor contacting engagement with the inner walls of the sleevemembers 15at right angles to the split portions 16. Ears e5 18, carried by andrearwardly projecting in spaced parallelism in the lowermost end of thesleeve members 15, are provided with aligned openings to accommodate theextremities of a fulcrum bar 19 carried adjacent the lowermost edge ofthe body end or tailgate 20 and from which the latter may be swung tooccupy Vertical and horizontal planes.

The hoisting or elevating mechanism, 211- luded'to in the foregoing,comprises revolvably mounted square threaded lifting shafts 21 passedthrough bearings 22 and 23 located at spaced intervals upon the truckbody 11. Bevel gears 24 are carried upon the lowermost ends of each ofthe lifting shafts 21 for engagement with correspondingly constructedright angularly disposed ears 25 carried upon the extreme ends of ashaft 26 appropriately journaled beneath the floor of the wagon box orvehicle body. A worm gear 27 carried by the shaft 26 is meshinglyengaged with a worm 28 carried upon a power transmitting rod 29 leadingfrom a power take-off mechanism, not shown, to be inw .Operativeconnection between the sleeve cludedupon the particular equippedvehicle.

I substantially as illustrated in Figure 3' of the drawings.

From the foregoing description and accompanying drawings, it isunderstood that rotary mot1on of the shafts 21 in different directionswill cause'the endgate'20 to occupy a horizontal position. When theendgate is disposed inthe full line position, packages of great weightmay be rolled or otherwise shifted alongthe .floor of the wagon box orbody and on to the endgate whichnow forms an extension for the floor.

. The hoist mechanism is then actuated to lower the endgate until sameis disposed in a position similar to that suggested in dotted lines inFigure 2 of thedrawmg's. The parcels may then be removed. It is also to,be noted'that heavy parcels may be placed upon the enggate-when in thelowered position and elevat to occupy a. position in alignment with thefloor or bottom of the wagon box and submipently rolled within the wagonbox with t e utmost ease. Itis to be noted that the truck driver ordeliveryman will be relieved from all of the customary lifting strain inthe removing and replacing of articles of drayage.

As suggested in Figures 1 and 2 of the drawings, the conventional formsof latch mechanisms and supports may be employed to hold the endgate ina vertical osition shown 1n Figure 1 and a inst disp acement from thehorizontal position shown in Figure 2. The invention is susceptible ofvarious changes inits form, proportions and minor detai s ofconstruction, and the right is herein rved to make such 'clian s as prorly all within the scope of t e appen ed claims.

ribs attached to a su port, rollers journaledl at the lower ends 0 thebars and disposed inlanes at right angle to the ribs, sleeves sli ablymounted u n the bars, said sleeves being provided wit longitudinally disosed slots which receive the ribs, said s eeves ada ted to receive therollers, rotary liftingshaf ts disposed parallel with the sleeves,traveler members carried by the shafts and connected with the sleevesand means for simultaneously rotatin the shafts.
